Description

Technical Field

[0001] The present invention relates to the technical field of electrocardiogram (ECG) acquisition, and more particularly to an intelligent ECG acquisition support system and an application method thereof. Background Art

[0002] The position of the ECG leads is crucial for accurately assessing the electrical activity of the heart, and usually includes limb leads and chest leads; the limb leads include the right hand, left hand, right foot, and left foot. These electrodes are used to collect electrical activity from different locations on the upper and lower parts of the body to form different lead combinations. The position of the limb leads is the most basic electrode setting in the ECG, which can show the overall electrical activity of the heart; the chest leads include six electrodes, which are placed on specific parts of the chest, and the positions are as follows: V1: 4th intercostal space at the right sternal margin, V2: 4th intercostal space at the left sternal margin, V3: midpoint between V2 and V4, V4: 5th intercostal space at the left middle clavicle line, V5: 5th intercostal space at the left anterior axillary line, and V6: 5th intercostal space at the left middle axillary line;

[0003] At present, the conventional practice for ECG acquisition is to configure a large number of electrodes, and attach the electrodes one by one to the corresponding positions of the human body through film during acquisition. The accuracy of the electrode attachment position depends on the doctor's experience, and if the electrode falls off during use, it will directly lead to acquisition errors; and some devices use an intelligent ECG acquisition system that relies entirely on visual positioning. In actual application, it still requires too much manual intervention, because when the fat on the skin surface of the ribs reaches a certain thickness, it is difficult to distinguish by vision, and thus cannot be recognized; and some ECG acquisition devices that use a dot matrix pressing head method can eventually achieve position calibration, but the number of points that need to be collected during the calibration process will be large, and the efficiency will be very low. Therefore, there is a need for an intelligent ECG acquisition bracket system and application method that can better solve the above problems and enable self-service and efficient ECG acquisition.

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the following will be a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments.

[0029] The intelligent ECG acquisition support system of the preferred embodiment of the present invention is as follows: Figure 1 See also Figure 2-Figure 6 , including a collection bed 1, on which are provided limb ECG collection units 2 corresponding to the limbs of the human body, a chest ECG collection unit 3 corresponding to the chest of the human body, and a control host 4. The limb ECG collection units 2 and the chest ECG collection unit 3 are both connected to and controlled by the control host 4; the chest ECG collection unit 3 includes an outer cover 30 corresponding to the chest of the human body, the outer cover 30 is hinged to one end of the collection bed 1, and the edge of the outer cover 30 is provided with a first avoidance slot 300 for avoiding the neck of the human body and two second avoidance slots 301 for avoiding the two arms of the human body respectively. The collection bed 1 is provided with an outer cover flip motor 31, and the outer cover flip motor 31 is controlled by the control host 4 Control; The interior of the outer cover 30 is provided with a shooting camera assembly 39, six chest lead units, a sliding rod 33, and a transverse movement unit 34 that drives the sliding rod to move transversely; the chest lead unit includes an oblique adjustment arm 32, the upper end of the adjustment arm 32 is rotatably mounted on the sliding rod 33 and is provided with a pressure adjustment assembly 35 for adjusting the oblique angle of the adjustment arm 32 and detecting pressure, and the sliding rod 33 is provided with an adjustment unit 36 for adjusting the position of the adjustment arm 32; the middle part of the adjustment arm 32 is provided with a telescopic unit 37 for changing its length, and the lower end of the adjustment arm 32 is rotatably provided with a rib monitoring roller 38, the outer surface of which is provided with a detection electrode 380;

[0030] The limb ECG acquisition unit 2 (using four C-shaped positioning seats with upward openings and sampling electrodes disposed therein) performs limb lead detection on a person lying on the acquisition bed 1. After receiving the signal from the limb ECG acquisition unit 2, the control host 4 controls the outer cover 30 to flip and place it over the chest of the person. The camera assembly 39 takes a picture of the person to determine the person's outline size and the position of the sternum. Based on the obtained data, the adjustment unit 36 is controlled to adjust the position of each adjustment arm 32 on the sliding rod 33 and define the adjustment stroke for fine adjustment of each detection electrode 380. Based on the person's chest outline size and the position of the sternum, the width of the ribs can be determined, and then an adjustment stroke approximately perpendicular to the ribs can be determined. This stroke includes the precise intercostal position. In this way, a rough adjustment range in the form of a bar can be obtained, and interference caused by the thickness of the chest sebum can be effectively reduced.

[0031] Then, according to the adjustment stroke, the telescopic unit 37 controls the adjustment arm 32 to extend to the maximum value, and the pressure adjustment component 35 adjusts the inclination angle of the adjustment arm 32 so that the rib monitoring roller 38 fits and presses the human body. At this time, the rib monitoring roller 38 is located at the far end of the adjustment stroke; then the telescopic unit 37 gradually controls the adjustment arm 32 to shorten until the rib monitoring roller 38 reaches the near end of the adjustment stroke. During the movement, the pressure adjustment component 35 detects the pressure value and generates a pressure curve corresponding to the rib distribution. The precise position is determined according to the pressure curve. Then, the telescopic unit 37 controls the adjustment arm 32 to extend so that the rib monitoring roller 38 returns to the precise position. The pressure adjustment component 35 adjusts the pressure so that the pressure of the rib monitoring roller 38 on the human body reaches the set pressure value. After the detection is completed, the control host 4 controls the outer cover 30 to open and controls the multiple adjustment arms 32 to reset.

[0032] By applying the method of the present application, the interference caused by the thickness of the chest sebum can be effectively ignored. At the same time, it has high accuracy and intelligence, and can perform accurate ECG collection of limb leads and chest leads in a self-service manner without the need for medical staff intervention, which greatly saves personnel costs.

It is small in size and can effectively resist external interference, ensuring stable adjustment.

[0034] Preferably, a transverse shaft 322 is provided at the end of the support rod 320, and the transverse shaft 322 is provided with a metal bearing 323 for mounting the rib monitoring roller 38; the rib monitoring roller 38 adopts an inflatable rubber wheel, and the inner ring is provided with a conductive electrode 381, and the conductive electrode 381 is connected to the detection electrode 380 (which can be connected through an electrical connection line); a wire 3201 is passed through the support rod 320, and the conductive electrode 381 is electrically connected to the wire 3201 through the metal bearing 323; the structure is simple and the electrical transmission reliability is good.

[0036] With this structural design, the structure will be very compact, ensuring that the sliding sleeve 324 can slide along the sliding rod 33 while the support rod sleeve 321 can be adjusted in inclination. The force relied on for adjustment comes from the downward pressure provided by the C-shaped fork. This part of the pressure is detected by the pressure sensor and relies on the elastic member 350 to provide elastic buffering. At the same time, the elastic member 350 also makes the contact reliability better, which is reflected on the human body, and can better fit the human body and perform controllable adjustment of the pressing force.
